Mechanical Aquarium

Love it, and love to watch the fish swim

Ingenious linkage inside the "fish" allows them to "swim" when they rotate round the "tank". Two minor problems were incurred. 1) The pre-wound spring was tricky to locate in its split wheel, even with the tool allowing the builder to unwind it from the centre. This was solved successfully, by pushing the centre turn sideways, then rotating the whole assembly round and round, rewinding each turn outside the previous one, until all was wound onto the small wheel. 2) The release escapement (a block of three layers), which was a bit sticky at first, needed careful sanding so the pivot was free to allow movement.

Det var lite klurigt att få alla kugghjulen till att gå smidigt Smörjan som levererades räckte ej till men jag smorde med paraffinolja och då fungerar bygget problemfritt.
